SPECIFICATION forming part of Letters Patent No. 426,796, dated April 29, 1890.

Application filed June '7, 1889. Serial No. 313,464. (No model.)

. To all whom it may concern.-

Be it known that I, CARL FRANZEL, proprie tor of a factory, a subject of the Emperor of Austria, residing at Domstadtl, Moravia, in Austria, have invented certain new and useful Improvements in a Grain Scalpel, Sheller, and Peeling-lvlachine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being made to the accompanying drawings, in which Figure 1 shows a front View of my apparatus partially in transverse section and partially in elevation. Fig. 2 shows a section on the line A B of Fig. 1. Fig. 3 shows a section on the line C D of Fig. 1. Fig. at shows a plan of the frame-work with its bracing rods and the hearings on a reduced scale. Fig. 5shows an inside'view of one of the clamping-rings carrying the stone cylinder. Fig. 6- shows a transverse section of Fig. 5.

The principal new feature of the present invention is thesubstitution forthe usual heavy millstone rotating in a casing closed on all sides of a light cylindric grinder open on both sides, made of stone, stone-mass, or emery, which is mounted on a driving-shaft by means of annular clamping-rings, of a peculiar shape, holding said stone cylinders by means of dovetailed notches. This stone cylinder grinds against a drum open on one side and covered with a perforated plate or wiregauze and provided with a stationary lid or cover, whereon a regulating sliding plate is arranged, which,provided with a slit, enables me to raise or lower the outlet, so that the treated product can be withdrawn at pleasure or as may he found necessary. Oompared with the machines in use up to this time, this arrangement presents the following advantages: In the first place, a considerably-smaller driving-force is required. In the second place, it works continuously without requiring the stone to be dressed anew and combines therewith an increased efficiency for scalping and shelling grain or peeling barley, and in the third place it gives finer work and better results than the machines hitherto used.

As shown in Figs. 1 and 4, the drivingshaft 0 is carried by the standards (I. 0., which are braced by the rods 1) b b 11, which are screw-threaded and held in position by nuts. On this shaft 0 a cylinder, open on both sides and made of stone, stone-mass, or emery d, is keyed by means of clamping-rings 6. These rings 6, Figs. 5 and 6, carry at their periphery dovetail notches e, engaging in similar dovetails in the stone cylinder, Fig. 1. Plates e are arranged on the clamping-rings so as to close the cavity of the stone cylinder cl. The clamping-rings e and the plates 6 are rigidly connected by means of bolts 6', provided with nuts at their threaded ends.

Around the stone cylinder d, I arrange a drum Z, which is rigidly held together by means of a suitable number of bolts passing through the side pieces and the circumferential rim or cover, thus firmly connecting all the parts. This drum is lined all around with a perforated plate or wire gauze 3. The drum Zis provided with suitable bearings 13 q, one on each side. These bearings are hollow and cylindric in form and are sufficiently large so that they may surround the operating-shaft 0 without touching the same. The bearing-pieces p and q are secured to the side walls of the drum Z by means of suitable bolts and nuts, as clearly shown in Figs. 1 and 3. The drum Z is supported by these hearings on journals 7 8, arranged one on each side of the apparatus upon supportingbars t 'v, to which they are bolted. The supporting-bars t rest upon the rods 1) b, which are secured to the standards a a. The supporting-bars t 'v are secured in place upon the rods 1) b by means of suitable pins or keys.

The outer end of the bearing 19 is covered by a plate 17, fitting loosely around the shaft 0 and bent outwardly at its upper end, thus forming an inlet-passage S, which leads to the interior 12 of the drum.

On the bar o bolts to are riveted for holding the stationary cover 00, which closes one side of the drum. On this stationary cover a: is secured the sliding plate g, which is arranged to move in guides formed in the cover and which is provided with the eccentric slot .2, which forms the outlet passage.

When the sliding plate y is moved or r0- tated to the right or left by means of the handle 1, the outlet is raised or lowered as the slot .2 is turned in either direction, as will be seen in Fig. 2, which causes a larger or smaller amount of grain to accumulate in the drum before discharging, and this amount can be regulated as desired by simply adjusting the sliding plate y. The sliding plate 1 may then be securely held in place by means of the binding-screws 10.

The movable drumZ is inclosed in a stationary outer casing 11, fixed on the rods 1) and l).

15 is a ring keyed on the shaft 0, which closes the opening into the bearing (1 from the inside of the drum.

On the main shaft 0 are arranged two pulleys f and f for the transmission of the motive power, and also the pulley g, which transfers power to the pulley m and the gearwheel at, which gears with the toothed wheel 0, arranged .on the drum Z, and thus imparts to this drum a rotary motion inverse to that of the stone cylinder cl and at thedesired velocity. The drum Z should make about sixteen revolutions per minute, while the stone cylinder (Z makes in the same time from two hundred to two hundred and forty revolutions. On the other side of the shaft 0 the pulley 7L is arranged, transferring motion by means of the pulleyi to the axle 7t of the fan 7. The fan 7 removes, through the opening 6, the air entering by the air-holes 4, by the bottom-opening 5, and by the inlet and out-- let, together with the grain-shells, the dust, &c., in the direction of the arrow, Fig. l. The feeding of the grain to be treated takes place through the opening of the bearing 1), at 8, into the space 12, the outlet being on the opposite side through the opening .2 into the conduit 9.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a grain seal per, sheller, and peeling-machine, the stationary cover a:, with the regu' lating sliding plate y, and the eccentric slot ,2, for increasing or diminishing the accumulation of the grain in the mill, as maybe found necessary, substantially as heretofore shown and described.

In witness whereof I hereunto set my hand in presence of two witnesses.
